"Why does my iPod turn off when I volume up the iPod?"에 답변This might mean several things: 1. The down button is physically pressed (Or electrical contact has shorted) 2. The headphone jack is sensing a volume button press (less likely) 3. Software is corrupt (an update might solve this) 4. Bluetooth remote. 5. If your iPod is jailbroken maybe you set something wrongly (an update/restore might solve this also)
